PADS 9.5 now allows creation of virtual pins or star points. This is a great new feature which makes DDR routing much easier. It allows you to define a star point which branches out to multiple receivers. High-speed rules such as length matching can be defined to tune the different branches to the correct length.

Virtual Pin

Associated nets support was added in PADS 9.4 and allows design rules to be assigned to several nets that are connected by components such as a series resistor or a resistor pack. Design rules that can be set include length and differential pair rules. Associated Nets may be defined automatically through a number of different methods, or manually. The length of the discrete component that associates or “combines” the nets can be included in the associated net length calculation.
The Associated Net and Virtual Pin features are tied to the Advanced Rule Set option.
